316l Data Sheet

316L stainless steel is a popular material used across a variety of industries. It is an austenitic stainless steel, which means it possesses excellent resistance to corrosion and high-temperature oxidation. In addition, it has good strength and toughness at both high and low temperatures, making it an ideal choice for many applications.

One of the key advantages of 316L stainless steel is its versatility. It can be used in a wide range of environments, from marine and chemical processing to medical equipment and food processing. Due to its excellent corrosion resistance, it is commonly used in harsh environments where other materials would quickly become damaged.

Another advantage of this material is its excellent weldability. This allows for ease of fabrication and makes it a popular choice for a variety of fabrication applications. It can also be used in high-temperature applications due to its good heat resistance.

What is stainless steel AISI 316 / AISI 316L?

Stainless steel AISI 316 and AISI 316L are two common grades of stainless steel that belong to the AISI (American Iron and Steel Institute) 300 series. Both grades are very similar in composition and have similar properties, with the main difference being the carbon content.

AISI 316:

AISI 316 is an austenitic stainless steel grade.

It contains approximately 16-18% chromium, 10-14% nickel, and 2-3% molybdenum.

The addition of molybdenum enhances its corrosion resistance, particularly against chlorides and other corrosive agents.

AISI 316 offers excellent overall corrosion resistance, high tensile strength, and good mechanical properties.

It is commonly used in marine environments, chemical processing, pharmaceutical industry, and applications where corrosion resistance is critical.

AISI 316L:

AISI 316L is a low carbon variation of AISI 316.

It contains a maximum of 0.03% carbon, which helps to eliminate carbide precipitation during welding, reducing the risk of intergranular corrosion.

AISI 316L offers the same corrosion resistance and mechanical properties as AISI 316 but with improved weldability.

It is often preferred for applications that involve welding or require resistance to sensitization and intergranular corrosion.

AISI 316L is commonly used in industries such as chemical processing, pharmaceuticals, food processing, and medical devices.

Both AISI 316 and AISI 316L are versatile and widely used stainless steel grades due to their excellent corrosion resistance, high strength, and wide range of applications. The choice between AISI 316 and AISI 316L depends on the specific requirements of the application, particularly the need for weldability and resistance to intergranular corrosion.

The properties of AISI 316 / 316L stainless steel sheets

• Corrosion Resistance: AISI 316/316L stainless steel sheets offer excellent corrosion resistance, especially in environments containing chlorides, acids, and other corrosive substances. They have superior resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking.
• High Temperature Resistance: These stainless steel sheets exhibit good high-temperature resistance, allowing them to maintain their mechanical properties and corrosion resistance at elevated temperatures. They can withstand intermittent temperatures of up to 870°C (1,600°F) and continuous use at temperatures up to 925°C (1,700°F).
• Strength and Durability: AISI 316/316L stainless steel sheets have high tensile strength and good toughness. They offer excellent structural integrity and durability, making them suitable for various demanding applications.
• Weldability: AISI 316L stainless steel sheets, in particular, have improved weldability due to their low carbon content. The reduced carbon content helps prevent carbide precipitation, minimizing the risk of sensitization and intergranular corrosion during welding.
• Formability and Machinability: These stainless steel sheets are readily formable and can be easily fabricated into desired shapes and sizes. They can be cut, bent, welded, and machined using standard fabrication techniques.
• Hygienic and Sanitary Properties: AISI 316/316L stainless steel sheets are commonly used in the food and pharmaceutical industries due to their hygienic properties. They are resistant to bacterial growth and easy to clean, making them suitable for applications requiring strict hygiene standards.
• Aesthetic Appeal: AISI 316/316L stainless steel sheets have a smooth, polished surface finish that provides an attractive appearance. They are often used in architectural and decorative applications.

Is AISI 316 / AISI 316L stainless steel magnetic?

magnetic in their annealed or fully austenitic state. This means that they do not exhibit magnetic properties when in their most common form. However, it's important to note that the magnetic response of stainless steel can be influenced by various factors, including the manufacturing process, cold working, and composition variations.

In some cases, AISI 316/316L stainless steel may exhibit weak magnetic properties when subjected to cold working processes such as bending, machining, or welding. Cold working can introduce structural changes in the stainless steel, causing the formation of martensite, a magnetic phase. However, even in these cases, the magnetism is generally quite weak.

Furthermore, the carbon content in AISI 316L stainless steel is lower than in AISI 316, which can further reduce the likelihood of magnetic properties.

To summarize, while AISI 316 and AISI 316L stainless steel are primarily non-magnetic, they may exhibit weak magnetic properties when cold worked. For most practical purposes, they are considered non-magnetic, but it's always advisable to test the specific material if magnetic properties are a critical consideration for a particular application.

Density of AISI 316L

The density of AISI 316L stainless steel is approximately 7.98 grams per cubic centimeter (g/cm³) or 7980 kilograms per cubic meter (kg/m³). This value represents the average density of AISI 316L stainless steel at room temperature. It's worth noting that the density may vary slightly depending on the specific composition, manufacturing process, and any additional alloying elements present in the stainless steel.
